Use of optical brighteners and phthalocyanines as photosensitizers

摘要

A photovoltaic cell comprising an electrically conductive element to which one or more titanium dioxide layers have been applied, to which titanium dioxide layers a photosensitizer having at least one interlocking group (preferably a COOH containing group) has been applied (being hereinafter defined as component a); characterized in that the photosensitizer is selected from optical brightener compounds and phthalocyanine compounds.
